7 Claims. (Cl. 20 42) This invention relates to a horizontally slidable Window assembly, and it more particularly relates to an assembly wherein Ithe window is also adapted to be pivoted.

Horizontally slidable windows have gained increasingly wide acceptance and many new homes are provided therewith. rIhis is due to many factors among which are their relative ease of manufacture, their moderate cost and their ease of installation. been found that it is most difficult to wash such windows because of the difliculty in reaching all areas ofthe outer surface. To adequately wash such windows, it is usually necessary to either remove the window panels from the window frames or to wash the windows from the outside. Removing and replacing the window panels is an irksome and tedious job especially for a housewife, while washing the windows from the outside is a hazardous and awkward procedure which most people would prefer to avoid.

It is `one object of the present invention to overcome the aforesaid ditilculties'rby providing a horizontally slid able window assembly wherein the slidable window may also be pivoted to extend into the room and thereby be easily accessible on both sides.

Another object of the present invention lis to provide a window assembly of the aforesaid type which is relatively simple in structure, easy and economical to manufacture, easy to install and easy to use.

Other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

Referring in greater detail to the various figures of the drawings wherein similar reference characters refer to similar pants, there'is shown a window assembly, generally designated 10, comprising a rectangular frame 12 in which is positioned one `stationary window panel 14 and one slidable window panel 16, each of these panels comprising a rectangular frame with a glass pane therein in the standard manner. i

The frame 12 includes an elongated channel 18 which acts as a yguide for the sliding movementk of panel 16 into and out of closed position. This guiding action is provided in conjunction with cylindrical guide feet (more fully described hereafter) mounted on a flange 22 extending laterally from an upward extension 24 of the frame of the panel 16. An upright llange 26 also extends upwardly from the 'panel frame but in spaced relation to extension 24. The llange 26 is higher than extension 24 and acts as a cover for the upper edge of the slidable panel.

The extension 24 is also provided with a longitudinal channel 2S in which is positioned la weatherstrip 30. This rweatherstrip 34D is preferably made of wool fibers although any other material such as metal, vinyl, polyethylene or the like may also be used. The channel 28 is open on its inner side and the weatherstrip 30 projects throughl this opening into a position where it slidably abuts against the adjacent side wall defining channel 18.

The aforesaid cylindrical guide yfeet supported by the flange 22 are indicated at 32, each of these guide feet 32 being secured to the flange 22 by means of rivets 34 or the like. The feet 32 slidably engage the inner surfaces of the two opposite side walls deiining channel 18.

At the rearward edge of ilange 22 is secured a pivot member 36, this member 36 being connected to the flange 22 by a rivet 38 or the like. The member 36 is provided with a pivot linger 40. Y

At the lower edge of panel 16 are provided a pair of cylindrical guide feet 42 similar to feet 32 except that they are provided with undercut V-shaped notches 44. These notches are provided to engage an upstanding guide rail 45 extending up from the bottom portion of theA window frame 12.

At the rear end of the lower edge of the panel 16 is provided a plate 46 retained in position by a screw 48 or the like. The plate 46 is provided with a depending pivot finger 50. The plate 46 is also provided with an undercut recess 52 to permit the plate 46 to be raised out of engagement with .the guide rail 45.

Positioned on the bottom portion of the window frame, to the right of but adjacent the left hand end of the panel 16 when in closed position, is a cam block 54. This block 54 includes an inclined edge 56 and a straight top edge of rail 45. The block itself is linearly adjustable by 'means of a lateral flange 60 having an elongated slot 62 through which extends a set screw 64. The screw '64, when loosened, acts as a Vguide topermit linear adjustment of the block 54 in either direction for the Vlength of the slot 62. Then when 'the blockhas been adjusted to the desired position, the screw 64 is tightened to hold the block securely in place; Y Y

The bottom portion of window pane 16 is also provided with a longitudinal channel 66 having a side opening from which projects aV weatherstrip 68 seated in the channel. The strip 68 is similar to the strip 30 and is adapted to sealingly abut an upstanding ange 70 on the lower portion of the window frame.

Whereas the panel 16 is movable relative to the window frame 12, the panel 14 :is xed in the window frame and ispositioned behind the panel 16 to permit overlapping l78. The cam track vis stepped at the junction of the slot portions 74 and 76, as indicated Vat 80. This step 80is necessary because when the relatively Wide member 36 rides in wide slot portion`74 the parts are in a different section of the mathematical `curve of rise than when the relatively narrow linger 40 rides in the narrowslot portion 76. The step Si) takes care of the diierential and therebykeeps thercurve of rise smooth and' continuous. An vopstanding stop flange 82 is provided at the end of thecam track. Y Y

On the, inner lower edge of window frame 12, in vertical alignment with cam track 7 2, is a similar cam track 84.V VThis vcam track 84 is also provided with an elongated slot but only a minorV portion thereof is relatively mentary to that of Wall 128 so that it is slidably engageable therewith to limit the forward movement of the panel 16 (as illustrated in FIG. 22).

In operation, when it is desired to merely open or'close the window, this is done in the-normal manner by easily sliding the panel 16 back and `forth to the desired position. However, when it is desired to move the window into the pivotal position, this can be easily done by giving the panel 16 an extra shove. This provides the slight additional force required to raise the panel on its cam tracks whereby member 36 and thetinger 40, which is of rectangular crossfsectional shape, are guided iirst by the wide slot portion 74 and then by the narrow slot portion 76. At the same time, the finger 50, which is also of rectangular cross-section, engages first in slot portion 86 and then in slot portion 88 as it moves up the inclined' track 84. Simultaneously, the foot 42 at the forward end (or right hand end as viewed in FIG. 4) moves onto the cam block 54 while the notch `44 rides over auxiliary cam portion 59. 'Iihe upward force exerted by the block '54, in -conjunction with the force applied by cam track wide, as at 86, while the major portion is relatively narrow, as at 88. At the end of slot portion 88 is provided a circular opening 90, similar to opening 78.V The cam Atrack 84, is furthermore, not stepped but extends in a straight inclined directionV up Vto aA straight plateau portion, the opening90 Vbeing positioned in this plateau portion.

At the rightV hand' edge of panel 16 (as viewed in FIG'. l) there is provided a latch means 92. This latch means comprises a generally U/-shaped handle 94 having one Iarm 96 adapted to engagera lateral ange 98 on the corresponding vertical edge of the panel V16, and having its other arm 100 provided rwith two extensions 102 and 104 (see FIG. 23). The extension 102 is provided at its end with an enlarged, cylindrical portion 106 engageable within a groove 10S in the panel 16 whereby there is formed a hinged joint between the latch means and the panel. The other extension 104 is provided with a hooked end 1110 releasably engageable withv a flange 112 on the corresponding vertical edge of the window frame 12. A

spring`114 is connected 4to arm 100 and bears against the edgeA of ange 98. ,n This spring, therebyrbiases the latch into locking position against flangeV 112 (as indicated in vfull line in FIG. 23).

The left hand vertical edge of panel 16 (as Viewed in FIG. l) is provided with a channel 116 in which is prof vided a weatherstrip 118 similar to that shown at 68. The opposite vertical edge of panel 16 isalso provided with a channel 120 having a weatherstrip 122 of similar type. This channel 120 is providedyin the rearward edge of the framework of the panel 16 (see FIG. 22) and the Weatherstrip 122 is adapted to frictionally engage against a straight wall 124 defining one edge of the open inner side of a hollow, vvertical post 126 in the window frame. This wall 124 is spaced inwardly from Vthe plane of the inclined wall 128 dening the Opposite edge of the open inner side of post 126. n

.The rearward edge of the framework of panel 16, in

-addition to channel 120 and Weatherstrip 122, is provided with a ange 130 having an inclination'comple- 76, acts to lift the -entire panel 16 within the window frame. Y l

VThe iingers40 and 50 move along their respective slots Vuntil they reach their respective openings 78 and 90.

Since the lingers 40 and 50 are rectangular in crosssectiomthey cannot be rotatedwithin their respective slots until they reach their respective openings 78 and 90. Then, however, they can be rotated into the full line- Ypositions shown in FIGS. l5 and 18. In these positions,

they are locked against movement out of the openings.

When the lingers 40 and 50 are within the openings 78 and 90, they are in pivotal position. Therefore, the panel 16 can be pivoted into a position transverse to the windowframe (as indicated in FIGS. 14 and 17). In this pivotal position the fingers are in the locked position within their respective openings (as shown in FIGS. 15 `and 18 and as described above). Therefore, the panel can be pivoted to any desired positionwithout danger of falling out of the Window frame. Thereafter, when it is desired to either remove the panel or to move lit back to closed position, the panel is pivoted back to its normal position parallel with the window frame, at which time the ngers 40 and 50 are again in position to slide into the slots of their respective cam tracks.

Obviously many modications and variations of the present invention are possible in the light of the above teachings. VIt is, therefore, to be understood that Within Vthe scope of the appended claims, the invention may be practiced otherwise than as specically described.
